srncrrrcarxon forming part of Letters 1 am No. 65 5,051, dated July 31, 1900. Application filed (ietober 17, 1898. Serial No. 693,719. (No model.)

To all whom it ma concern:

Be it known that I, ARTHUR W. B'nownn, a citizen of the United States, residing at New York, (Princes Bay,) in the county of Richmond and State of New York, have invented certain new and useful Improvements in Fountain-Spittoons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to dental fountainspittoons; and it consistsof certain improvements which will be hereinafter fully explained and then pointed out in the claims.

The object of my present invention is to generally improve this class of spittoons by rendering them more efficient and to overcome certain objections heretofore found exis a top or plan view thereof.

isting.

I have in the accompanying drawings illustrated the preferred embodiment of my invention in two different forms.

In said drawings, Figure 1 is a perspective View of a form of spittoon adapted to be connected to a dental chair and known in the art as an attached fountain-spittoon. Fig. 2

Fig. 3 is acentral Vertical sectional view of said spittoon, the section being taken on the curved line 3 3 of Fig. 2. Fig. 4 is a vertical sectional detail view of a portion of the spittoon-bowl, also on an enlarged scale, showing the water; sprayer or jet-tube and its guard-plate in side elevation. Fig. 5 is another detail view show ing the said water-sprayer and guard-plate in plan. Fig. 6 is a View, mostly in side elevationand partly in vertical section, of another form of fountain spittoon of the upright standard type. Fig. 7 is a vertical central sectional view of the lower or base portion thereof on an enlarged scale. Fig. 8 is a plan 'View. of said lower or base portion on the same scale as Fig.7.

I will first describe the attached spittoon illustrated by Figs, lto 5, inclusive. The spittoon-bowl A, which will be fully described hereinafter, is of peculiar and novel construction and is preferably detachably connected by way of its externally-threaded neck A to the outer end of a horizontal supporting-arm B, the inner end of which is swiveled tothe outer end of ahorizontal bracket-arm O. The inner end of the bracket-arm O is swiveled upon the upper end of an upright rod D, having vertically-adjustable and turning connection with the outer end of another bracketarm D, adapted to be suitably connected to a dental chair in well-known manner.

The supporting-arm D is hollow and at its inner end communicates with and is connected to a metal pipe E, mounted to turn in the outer ment formin a chamber B which 0 ens into the pipe E. A pocket or cup 13 is formed in said chamber and constitutes the end of the conduit b of the supporting-arm. A small or interior waste-pipe B passes through the bot tom of the pocket B and through the pipe E. I prefer to detachably fit the said interior waste-pipe B in an opening in the bottom of the pocket and provide it with a loop or handie I), by which it may be withdrawn when desired. A flexible pipe B (shown in dotted lines, Fig. 1) is connected to the lower end of the interior waste-pipe B and extends a considerable distance in the flexible waste-pipe E, thus forming a continuation of the interior waste-pipe B which does not interfere with the movement or flexure of said flexible waste-pipe E.

A holder orbowl F, preferably smaller than the spittoon-bowl proper and intended to support a drinking-glass and also serving other purposes, is supportedby an upright tube F upon the arm B directly over the enlarge'ment B, said tube F screwing into a I threaded opening in the top of said enlargement, with the chamberof which said tube size to carry off all the water used in the the lower extremity of its neck A.

ordinary flushing of the spittoon-bowl, and this is accomplished absolutely without noise. Inthis way the usual objectionable gurgling of the water in fountain-spittoons as heretofore constructed is overcome, because the air carried with the water through the tubular supporting-arm B escapes to the open air. byway ofthe'tube F, instead of being car-- tied down into the waste-pipe, Where it would become entrapped and interfere with and back up the water in said waste-pipe.

Should the supply of water to the spittoonbowl for any reason be too great to be car-' ried ofi by the interior waste-pipe, the sur plus water will overflow the pocket B and escape by way of the outside waste-pipe E.

When this occurs, the extra rush of water, maycause more or less noise, as in the ordi "nary form 'of'fountain-spittoon; but as this is not the'normal condition of the spittoon wh'en'in operation it is of little consequence. The top of thepipe F being at a point above the neck of the s'pittoon-bowl it will be impossible for the water to overflow said pipe "13" and bowlF.

The spittoon-bowl is constructed as follows:

The entire bowl, as usual, is circular in hori- "zonta1 section from the top of its rim A to The body or'side' of the bowl is curved outwardly at A inive'rtical sect-ion from about a line marked The-chief peculiarity of the bow-l lies in the fact that its bottom A is fiat and-amass horizontahfor a purpose farther "onto be made plain, and is curved inwardly and downwardly'at A and then merges into.

the tubular neck A, The flat bottom A "commences at about the line marked a and "extends to, say, about a on a practical1y- 'str'aightline, having a slight downward pitch I have disa 'c'ove'red'that 'for the purpose intended the pitch orinclination of the fiat bottom toward toward-the center of the bowl.

the 'ce'nt'eroft'he bowl should best be approxifrnatel'y three and one halfdegrees (3%) from the horizontahalthough this pitch may be varied slightly more or less. The inwardly and downwardly curved portion A of the.

bowl extends from the before-mentioned line d to assum where itmerges into the tubul-ai' nec'kAQ-which forms the central opening of t hebowl. Said curved portion A constitutes in yertical section approximately a quadrant offa circle the diameter ofwhich is approximately equal to the diameter of the tubular neck A. The rim A of the bowl is preferably rolled inwardly and downwardly.

"Anoverhanging' water-sprayer or jet-tube G'is'prov'ide'd for -flushing the bowl-with water,"a'nd' depen'dsfrom an upright supporting tube or sup'ply-pipe-H, which is supported in a short bi acket'B projecting from'the inner endof the supporting-arm B. Asshown, this supply-pipe H is supported independentlyof the bowls A and F. A flexible supply-pipe H" iscoupled to the lowerend of the supportingt'ube H, beneath the bracket Bfl' and extends and have more "sloping bottoms.

downwardly alongside the flexible waste-pipe E, both of these tubes, it will be seen, being located to one side of the spittoon-bowl instead of being connected directly thereto, as

is usual with fountain-spittoons of the attached type. The water-sprayer orjet-tube overhangs the spittoon-bowl and projects under therolledrim A 'thereof, the side of the outlet end of the tube resting against the inner side of the bowl under its rolled rim.

. For the purpose of placing the jet-tube in proper position under the rolled in and down rim of the bowl, and also for removing said bowl when desired, the lower portion of the jet-tube may have swiveling connection with itsupper portion, as by screw-threads g, Fig. 4. By this construction a jet orstream of water is delivered against the inner side of the bowl and covers the entire bottom'of the bowl with a thin film of water, which moves opening thereof, throughwhich'it passes after thoroughly flushing theibowl.

Owing to the novel constructionof theispittoon bowl, having the fiatbottomand'the partieular curve A about-its central opening, a much smaller quantity ofwater is'required to flush the bowlth'an is used by'spittoonbowls of usual construction, which are deeper This construetion also enables thewater to quickly pass out of the bowl after it has properlycirculatedaround and flushed the'same. As the outlet end of. thewatei sprayer projects under the rolled rim of the bowl the water spirally around the bowltoward the central cannot be seen issuing from saidsprayer, nor

can that portion of the inside of. the bowl which is not covered by the film of waterbe seen. Consequently person lookinginto thebowl when the same is being flushed practically cannot see any metal of the bowl'which is not covered by a thin film of water in circular motion.

Secured upon the jet-tube in rear of its'outlet openingis a guard-plate'G, which extends approximately at a right angle to that part of the bowl near which it is placed. .The

surface of saidplate near the side of the bowl danger of the water rushing overtlre riinof the bowl isavoided. A cock G ofany wellknown or suitable construction is employed for turning on and 01f :the supply of water an'd .for regulating theamount of thesame.

A'saliva-ejector cock land a drinking-waesaem ter cock 3 are supported directlyover the drinking-glass holder or bowl F by a pipe K, connected to the supporting-tube or supplypipe H. Depending from the saliva-ejector cock I is a saliva-ejector L, which is connected to said cock by way of its stem L. A nipple Z is provided on the saliva-ejector stem L for the attachment of a flexible tube L to the opposite end of which a mouth-tube L (see Fig. 1) is connected. A second nipple N opens into the stem L of the saliva-ejector above the ejector-nozzle Z, and is designed for the attachment of a flexible tube N, to

the opposite end of which is connected a syringe N The manner of supporting the saliva-ejector shown herein will form the subject of an application which will be a division of the present application.

The upright standard form of spittoon illustrated in Figs. 6, 7, and 8 is similar to the spittoon just described, so far as the bowls, the supporting-arm B, and parts carried thereby are concerned. Instead, however, of swiveling the supporting-arm B upon the arm C, the said supporting-arm is con nected directly to the upper end of an upright tube 0, adapted to slide up and down and turn horizontally in a tubularupright stand coupling 1? with the usual waste pipe or main,

(not shown, but which projects through an openingin the floor under the base.) Similar connection is made inside the base with the usual service pipe or main, and a flexible supply-pipe H, which may be coiled around the standard, conveys the water to the spittoon, as before described. In order to supply the spittoon with both hot or warm and cold water, two such connections Q may be provided, the one for hot or warm Water from any suitable source, such as a kitchen-range, and the other for cold water. Each of these connections or couplings Q Q is carried by short vertical pipes Q Q, supported in the base, and above the base these pipes communicate with a branch or connecting pipe R, to the center of-which the flexible supplypipe H is connected. Suitable valves S S are provided for turning on or ofi the water in the hot and cold water pipes, and the stems of these valves are preferably provided with foot-actuated levers or pedals S, which extend on opposite sides of the valve-stems. In this way either hot or cold water may be supplied to the spittoon, particularly to be drawn from the faucet J and syringe N, by manipulating the levers S S, or any desired mixture of hot and cold water may be secured.

of the same character as heretofore constructed. For example, the cock for con-- trollin the flush of the spittoon-bowl, as well as the cocks for the tumbler-supply and saliva-ejector, are completely removed from the neighborhood of the bowl and are en tirely out of the way of the patients head when using the spittoon. In this way a smaller bowl may be used than usual. "The spittoon-bowl has a very wide range of adj ustment, and owing to the supply and waste pipes being located to.one side of the bowl instead of being connected directly to it the bowl may be moved over the arm or seat of a dental chair in convenient reach of a patient without moving said pipes with it. The objectionable gurgling of the water, which has heretofore been a source of much annoyance, has been obviated. The construction of the bowl not only enables a smaller quantity of water to be used, as before stated, but its flat construction presents a pleasing appearance and is less bulky and more readily handled than spittoon-bowls of usual construction.

' It will of course be obvious that my improved spittoon-bowl may be used upon any suitable or well-known fountain-spittoon, and also that the particular construction herein shown and described may be altered in various ways while still keeping within the scope of my invention.

I claim as my invention-- 1. The combination, in a fountain-spittoon, of the tubular horizontalsupporting-arm swiveled at its inner end to a support, a spittoonbowl connected to the outer end of said supporting-arm, the discharge from said bowl being by way of said supporting-arm, arigid bracket projecting laterally from the inner end of said supporting-arm, a supply-pipe supported by said bracket, and an overhangformed in said chamber, and a smaller discharge-pipe inside the discharge-pipe and communicating with said pocket, substantially as and for the purpose set forth.
